A process of fixing the side chain button to the side chain button fixing jig of the embodiment of the present invention will be described as follows.

The worker fastens the base 1 to a sewing machine (not shown) using bolts or the like. Then, the operator rotates the knob 15a of the adjusting member 15 to move the position adjusting plate 13. The bracket 5 moves together with the position adjusting plate 13 moving. At this time, the needle insertion groove portion 5a of the bracket 5 is set to be placed at a position where the needle of the sewing machine is inserted.

In this state, the operator closely contacts a portion of the side surface (outer circumferential surface) of the button with the button supporting portion 11a of the second button supporting member 11 in a state in which the side loop button is raised.

And a separate switch (not shown) is operated to operate the driving source 7. The first button supporting member 9 moves in a direction in which the first button supporting member 11 is brought close to the second button supporting member 11 while the driving source 7 is operated. Then, the button supporting portion 9a of the first button supporting member 9 is brought into close contact with the opposite side (outer peripheral surface) of the side ring button. At this time, one side of the side chain button is in close contact with the engaging jaw 9b of the first button supporting member 9 and the engaging jaw portion 11b of the second button supporting member 11, and the side chain button is held in a fixed posture. Particularly, the tapered portion 9c of the first button supporting member 9 and the tapered portion 11c of the second button supporting member 11 hold the side ring button firmly fixed without falling outward.

At this time, the hook (not shown) of the side loop button is disposed at the lower portion of the needle insertion slot 5a. Thus, the sewing machine is ready for sewing. When button sewing is completed, the switch (not shown) is operated again so that the driving source 7 is operated in the opposite direction.

Then, the first button supporting member 9 is moved in a direction away from the second button supporting member 11, and the side loop button is disengaged.

In this embodiment of the present invention, the posture of the button can be improved because the posture of the side ring button is always kept fixed at the set position. Particularly, since the worker simply carries out the simple operation of bringing the side loop button into contact with the button supporting portion 11a of the second button supporting member 11, the work flow is reduced and the skill is not required, so that the productivity can be further improved.

In addition, according to the embodiment of the present invention, the first button support member 9 can be moved to the set position only, thereby preventing a safety accident of the operator.
